目標：在docker裏安裝mysql5.7並且可以通過工具訪問
安裝mysql：
查詢：
docker search mysql
下載（卡的直接停了再重新下，事實證明我卡了兩天都沒下好，Ctrl+C 停了再下30s）：
docker pull mysql
指定版本下載命令：
docker pull mysql:5.7
查看鏡像：
docker image ls
運行mysql
docker run -p 3307:3306 --name mysql5.7 -e MYSQL_ROOT_PASSWORD=abc123 -d mysql:5.7
參數：
-p 3307:3306 將主機3307端口映射到容器3306端口
-e MYSQL_ROOT_PASSWORD=abc123 設置遠程登錄的root用戶密碼爲abc123
--name 可選，設置容器別名
mysql 鏡像名稱
docker run -p 3307:3306 --name mysql5.7 -e MYSQL_ROOT_PASSWORD=abc123 -d mysql:5.7 --character-set-server=utf8 --collation-server=utf8_unicode_ci
指定編碼集
查看運行結果：
然後就跟本地安裝一樣，設置遠程登錄：
進入容器：
docker exec -it 39dfe9a9c741 bash
39dfe9a9c741是容器的短id
全部的命令行：
root@39dfe9a9c741:/# mysql -uroot -p
Enter password:

Bye
root@39dfe9a9c741:/# exit
exit
提取：
1：mysql -uroot -p //登錄mysql
2：select host,user,plugin,authentication_string from mysql.user;//查詢權限
3：GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;//更新登錄權限
4：ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';//設置密碼
5：flush privileges;//刷新權限
6：quit;//退出mysql
7：exit//退出容器
設置密碼有版本區分，具體可自行百度
都設置完畢後，重啓容器。
docker restart 39dfe9a9c741
因爲我是win7，用docker的話必須是虛擬機，所以查詢docker的ip：
docker-machine ip default
用Navicat連接一下：
